Arizona cliffrose [Purshia (=Cowania) subintegra]

The Arizona cliffrose is a plant that is well adapted to
the harsh environment of the desert. It is an evergreen shrub with pale
gray, ragged bark. It's leaves, twigs, and flowers are covered with dense,
short white hairs. The thick bark and white hairs enable the cliffrose
to insulate itself against the extreme heat of the desert climate. The
leaves also have a prominent vein, and the blooming five-petaled flowers
are white or yellow. This plant can grow up to 8 feet tall.

The Arizona cliffrose was listed with the scientific name
of Cowania subintegra, but has been reclassified as Purshia
subintegra. The plant is found on the low rolling hills of the central
Arizona uplands, between 2,000 and 3,600 feet elevation. It grows on somewhat
gravelly, sandy loam soil, apparently always associated with limestone.
Despite its common name, this species occurs on gentle slopes and terraces
more often than on very steep slopes. For nearly thirty years, this plant
was only known from one population. However, a second population was discovered
in 1970, and two more were located in 1984 and 1985. These populations
are widely separated in Mohave, Yavapai, Maricopa, and Graham counties.

There are various problems which threaten the existence
of the Arizona cliffrose. First of all, the plant reproduces at a very
low rate, which severely hampers any recovery of the shrub. Although one
population seems capable of viable reproduction, the others have have
been unable to adequately sustain themselves. Poor seed viability appears
to be a major factor with these latter groups. In addition, over 100 mining
claims have been filed in and around one site. The exploration that accompanies
these mines scrapes the surface of the ground, destroying plants and extensively
damaging the ecosystem. The grazing of cattle, mule deer, and feral burros
also threatens the cliffrose, and one population is jeopardized by urbanization.

Currently, three of the Arizona cliffrose populations occur
on Federal land, which makes the preservation of most of the plant's habitat
feasible. Management programs are attempting to supervise the mining activities,
and there is a possibility of fencing portions of the habitat to deter
grazing animals.

Siler pincushion cactus [Pediocactus sileri]

The Siler pincushion cactus is a tiny, inconspicuous plant
measuring up to 10 centimeters (4 in) in diameter. Given its size, this
endangered plant could easily be overlooked or stepped upon, if it were
not for its flowers. During the spring, bright yellowish flowers about
2.5 centimeters (1 in) in diameter will bloom and produce greenish yellow
fruit. Its straight or slightly curved spines are about 2.5 centimeters
(1in) long, and are dark brown which lighten to a white color with age.

The Siler pincushion cactus, which also has been known as
Echinocactus sileri or Utahia sileri, is found on the gypsum-
and calcium-rich soils of barren rolling hills. These soils are high in
soluble salts that, while ill-disposed to many plants, apparently suit
the needs of this cactus which does not compete well in other soils. Given
its predisposition to this highly specific soil type, it is probable that
the Siler pincushion never extended beyond its current range of northwestern
Arizona and southwestern Utah. Currently, this cactus sparsely populates
a narrow band stretching from southeast of Fredonia (Coconino County)
west into north-central Mohave County, Arizona, a distance of 70 miles.
This band is only 30 miles wide, and as of the mid 1980's, contains about
7,000 individual plants of the species.

The influence of human beings has adversely affected the
Siler pincushion cactus. Gypsum mining used to be a major menace to this
cactus, but potential uranium mining now seems to be a greater danger.
More than 200 uranium plans have been filed in the "Arizona Strip," 81
within the cactus' habitat. A rise in uranium prices could induce mining
companies to develop these claims. In addition, portions of the habitat
have been overgrazed by livestock, which also contributed to the erosion
of the slopes. The sparse, rolling hills are attractive sites for off-road
vehicles, which can further erode the delicate environment of the cactus.
Collectors also pose a considerable threat to this plant. Despite the
plant being considered a species of concern in the Convention on International
Trade in Endangered Species (CITES), and that all cacti are protected
under Arizona law, Siler pincushion cacti are not only sought by collectors,
but were even offered for sale in five plant catalogs between 1982 and
1984. Monitoring of the plant has been underway since 1986, and attempts
are being made to propagate the species in greenhouses to supply the commercial
trade.

Virgin River chub [Gila robusta seminuda]

The Virgin River chub is a medium-sized minnow that averages
about 8 inches in total length but can grow to a length of 18 inches.
It has a silvery, elongated body with a narrow tail and 9 to 10 rays on
the dorsal, anal, and pelvic fins. Scales are small and difficult to see.
It is an omnivorous fish, feeding on algae, aquatic and terrestrial insects,
crustaceans, and organic detritus.

This species is endemic to 134 miles of the Virgin River
in southwest Utah, northwest Arizona, and southeast Nevada. The Virgin
River chub presently occurs in only 50 miles of the mainstream Virgin
River between Mesquite, Clark County, Nevada, and La Verkin Creek near
Hurricane, Washington County, Utah. It is most common in deeper areas
where waters are swift with boulders and other sorts of cover. It occurs
over sand and gravel substrates in water less then 90 degrees fahrenheit,
and is very tolerant of high salinity and turbidity.

Studies indicate that a large decrease in range and numbers
of this species has occurred in the last century, primarily due to water
diversions and construction of Hoover Dam and Lake Mead. The potential
for additional irrigation projects continues to threaten the existence
of this species along with threats from the non-native red shiner and
deterioration of water quality from agricultural runoff. The Virgin River
Fishes Recovery Team of the Fish and Wildlife service is currently planning
recovery for this species and the Woundfin, another federally Endangered
fish found in the area.

Woundfin [Plagopterus argentissimus]

The Woundfin is a streamlined, silvery minnow about 3 inches
in length. It has leathery skin, without scales, and has sensors on its
lips. It feeds on algae, detritus, seeds, insects, and larvae and is commonly
found in shallow, swift flowing water over sand or gravel bottoms or in
adjacent pools. The reproductive cycle of this fish is believed to be
triggered by lengthening daylight, increasing temperature, and declining
spring runoff in late May.

Historically, the Woundfin's range was in the Colorado and
Gila river basins in Arizona, Nevada, and Utah. The woundfin now occurs
only in the Virgin River. The range extends 36 miles in Utah downstream
from the mouth of LaVerkin Creek, 35 miles through the northwest corner
of Arizona, and then 12 miles in Nevada down to Lake Mead. There are no
population estimates.

Dams, canals, reservoirs, and other water diversions for
irrigation and municipal uses have eliminated much of the woundfin habitat.
The red shiner, a non-native fish, continues to threaten woundfin populations
despite efforts to eliminate them from the Virgin River. Local authorities
have also tried to transplant the Woundfin into a number of rivers and
creeks but reproduction at these sites has not been successful.
